工作原理

Working principle

冷再生机主要有两种工作原理对应的类型，即就地冷再生机和厂拌冷再生机。

There are mainly two types of cold regeneration machines corresponding to their working principles, namely on-site cold regeneration machines and factory mixed cold regeneration machines.

就地冷再生机：在施工现场直接对旧沥青路面进行铣刨、破碎，同时按照一定比例添加稳定剂（如水泥、石灰、水等）、新集料和再生结合料等，然后进行拌和，使旧路面材料与添加的材料充分混合均匀，经过整形、压实等工序，形成新的道路基层或底基层。

On site cold recycling machine: At the construction site, the old asphalt pavement is directly milled and crushed, and stabilizers (such as cement, lime, water, etc.), new aggregates, and recycled binders are added in a certain proportion. Then, mixing is carried out to fully mix the old pavement materials with the added materials evenly. Finally, through shaping, compaction and other processes, a new road base or subbase is formed.

厂拌冷再生机：先将旧沥青路面材料铣刨、回收，运输到固定的场地，在专门的厂拌设备中，将旧料与新集料、再生结合料、活性填料、水等按照设计配合比进行搅拌混合，生产出冷再生混合料，再将混合料运输到施工现场进行摊铺、压实，形成新的路面结构层。

Factory mixed cold recycling machine: First, the old asphalt pavement material is milled, recycled, and transported to a fixed site. In a specialized factory mixing equipment, the old material is mixed with new aggregate, recycled binder, active filler, water, etc. according to the design mix proportion to produce cold recycled mixture. Then, the mixture is transported to the construction site for paving and compaction, forming a new pavement structure layer.

性能特点

Performance characteristics

成本优势：与传统的道路维修改造方法相比，可降低成本 20% - 46%，主要是因为减少了新材料的采购和运输成本，以及旧料处理成本。

Cost advantage: Compared with traditional road maintenance and renovation methods, it can reduce costs by 20% -46%, mainly due to the reduction of procurement and transportation costs for new materials, as well as the cost of handling old materials.

：旧铺层材料全部就地利用或回收利用，减少了新材料的开采，降低了对环境的破坏；无需对集料进行加热烘干，相比热拌工艺节省大量能源。

Environmental protection and energy conservation: All old pavement materials are utilized on-site or recycled, reducing the mining of new materials and minimizing environmental damage; No need to heat and dry the aggregate, which saves a lot of energy compared to the hot mixing process.

提高旧路等级：通过添加合适的材料和工艺处理，提高基层承载力，从根本上实现道路等级的提升。

Improving the grade of old roads: By adding appropriate materials and processing techniques, the bearing capacity of the base layer can be increased, fundamentally achieving the improvement of road grade.

结构完整性好：施工过程中形成的较厚铺层内，不存在传统施工中薄铺层间的薄弱界面，整体结构更加稳定。

Good structural integrity: Within the thicker layers formed during the construction process, there are no weak interfaces between the thin layers in traditional construction, making the overall structure more stable.

工期较短：无需运输旧料，施工过程一次性作业，简化了施工程序，大大节约了施工时间。

Short construction period: No need to transport old materials, one-time operation during the construction process, simplifying the construction procedure and greatly saving construction time.

应用领域

application area 

城市道路修复：城市道路因交通流量大、使用年限等原因，易出现裂缝、坑洼等病害，冷再生机可对其进行快速修复，恢复道路使用性能，延长使用寿命。

Urban road repair: Due to high traffic flow and service life, urban roads are prone to cracks, potholes, and other defects. Cold recycling machines can quickly repair them, restore road performance, and extend service life.

高速公路维修：高速公路维修时，采用冷再生技术可以在不中断交通或尽量减少交通影响的情况下进行施工，既保证道路正常通行，又节省维修成本和时间。

Highway maintenance: During highway maintenance, the use of cold recycling technology can be carried out without interrupting traffic or minimizing traffic impact, ensuring normal road traffic while saving maintenance costs and time.

乡村道路改造：能有效改善乡村道路老化、损坏等问题，提高道路质量，为村民出行提供便利，同时减轻建设成本压力。

Rural road renovation: It can effectively improve problems such as aging and damage of rural roads, improve road quality, provide convenience for villagers' travel, and reduce construction cost pressure.

机场跑道维护：对机场跑道因飞机起降荷载等因素造成的损坏进行修复，提高跑道的平整度和承载能力，保障飞行。

Airport runway maintenance: Repair the damage caused by factors such as aircraft takeoff and landing loads on the airport runway, improve the flatness and load-bearing capacity of the runway, and ensure flight safety.

停车场及广场修复：停车场和广场地面由于车辆频繁停放和行驶，容易出现破损，冷再生机可对其进行修复，恢复场地的使用功能。

Parking lot and square repair: Due to frequent parking and driving of vehicles, the ground of parking lots and squares is prone to damage. Cold recycling machines can be used to repair them and restore the functionality of the site.
